[0091] As Figure 2 shown, the bottom plate 2 is formed by splicing a plurality of modules, specifically, the bottom plate 2 comprises a battery swap module 21, a first connecting module 22, a second connecting module 23, a third connecting module 24 and a driving guide module 25. The modular bottom plate 2 is convenient to assemble, can assemble relevant modules according to the actual situation of the battery swap station, improves the assembly efficiency, only needs to assemble the modules on site, shortens the station building period, and even can be transported to the site as a whole after being assembled in advance, reduces the station building cost. Moreover, the modules of the bottom plate 2 are convenient for batch production, and the production cost is reduced.

[0092] As Figure 1 and Figure 2 shown, the number of the battery swap room 1 and the number of the battery swap module 21 in the embodiment are the same and are four, and the battery swap room 1 and the battery swap module 21 are arranged one by one. Specifically, the four battery swap rooms 1 are arranged at four corners of the battery swap station, and the two battery swap modules 21 are arranged along the vehicle driving direction, and the two battery swap modules 21 are arranged along the direction perpendicular to the vehicle driving direction, so that the four battery swap modules 21 and the four battery swap rooms 1 are arranged at the four corners of the battery swap station. The battery swap module 21 forms a battery swap station 26, and the battery swap station 26 is used for parking electric vehicles to perform battery swap operation.

[0093] In other alternative embodiments, the number of battery replacement modules 21 can be other and at least one, and multiple battery replacement modules 21 can be arranged in one direction (vehicle driving direction or perpendicular to vehicle driving direction) in sequence, or arranged in two directions. The number of battery replacement rooms 1 and the number of battery replacement modules 21 can be the same or different, one battery replacement module 21 can correspond to multiple battery replacement rooms 1, or one battery replacement room 1 can correspond to multiple battery replacement modules 21.

[0094] As shown in Figure 2 and Figure 3 , the battery replacement module 21 includes a containing groove 211, a wheel positioning area 212, a track mounting area 213, and a battery replacement equipment positioning area 214.

[0095] As shown in Figure 3 , the containing groove 211 is used to accommodate the lifting mechanism 57, and the positioning between the bottom plate 2 and the lifting mechanism 57 is realized. The lifting mechanism 57 is used to lift the electric vehicle, and facilitates the battery replacement operation of the battery replacement equipment on the electric vehicle.

[0096] Specifically, as shown in Figure 3 , the containing groove 211 includes a front containing groove 2111 and a rear containing groove 2112, and the front containing groove 2111 and the rear containing groove 2112 are arranged in the vehicle driving direction. The front containing groove 2111 is used to accommodate the front lifting mechanism to lift the front wheels of the electric vehicle, and the rear containing groove 2112 is used to accommodate the rear lifting mechanism to lift the rear wheels of the electric vehicle, thereby realizing the synchronous lifting of the front and rear wheels of the electric vehicle and ensuring the stability of the electric vehicle lifting process.

[0097] As shown in Figure 3 , the wheel positioning area 212 is used to mount the wheel positioning device for positioning the wheels of the electric vehicle, and the positioning between the bottom plate 2 and the wheel positioning device is realized. The wheel positioning device is used to realize the positioning of the electric vehicle relative to the battery replacement station 26, improve the accuracy of battery replacement, and improve the success rate of battery replacement.

[0098] Specifically, as shown in Figure 3 , the wheel positioning area 212 is located on the side of the rear containing groove 2112 away from the front containing groove 2111 in the vehicle driving direction. Therefore, the electric vehicle is first positioned and corrected by the wheel positioning device before entering the battery replacement station 26, so as to improve the accuracy of the electric vehicle parking and improve the success rate of battery replacement.

[0099] As shown in Figure 3 , the track mounting area 213 is used to mount the track 58 for the movement of the battery replacement equipment, and the positioning between the bottom plate 2 and the track 58 is realized. The track 58 is used to realize and guide the movement of the battery replacement equipment, so that the battery replacement equipment moves between the electric vehicle and the battery transfer device 17.

[0100] Specifically, asFigure 3 As shown, the track installation area 213 is located between the front accommodation groove 2111 and the rear accommodation groove 2112 in the vehicle running direction, so that the battery replacement device can be moved between the front and rear wheels of the electric vehicle, i.e. the battery replacement device can be moved directly below the electric vehicle to realize the battery replacement operation.

[0101] The track installation area 213 in the embodiment is provided with a first track 2131 and a second track 2132, both of which extend perpendicularly to the vehicle running direction, and the first track 2131 and the second track 2132 are arranged in the vehicle running direction. The battery replacement device is guided in the moving direction by the first track 2131 and the second track 2132, so that the movement of the battery replacement device is more accurate, and the success rate of battery replacement is improved.

[0102] In other alternative embodiments, only one track can be provided in the track installation area 213 to guide the moving direction of the battery replacement device.

[0103] As shown, Figure 3 The battery replacement device positioning area 214 is used to realize the positioning of the battery replacement module 21 and the battery replacement device, and realize the positioning between the bottom plate 2 and the battery replacement device, so as to improve the battery replacement accuracy of the battery replacement device.

[0104] Specifically, as shown, Figure 2 The battery replacement device positioning area 214 is located between the first track 2131 and the second track 2132 in the vehicle running direction. In the embodiment, the battery replacement device positioning area 214 is arranged on the stroke path of the battery replacement device, so as to facilitate timely identification of the position of the battery replacement device, improve the moving accuracy of the battery replacement device, and improve the success rate of battery replacement.

[0105] The battery replacement device positioning area 214 includes a magnetic strip installation area 215, which is used to install a magnetic strip for positioning the battery replacement device. The positioning between the bottom plate 2 and the battery replacement device is realized by the positioning magnetic strip, so as to improve the battery replacement accuracy of the battery replacement device. Specifically, the battery replacement device can be provided with a sensing part capable of identifying the positioning magnetic strip, and the moving position of the battery replacement device is determined by the sensing between the sensing part and the positioning magnetic strip.

[0106] As shown, Figure 2As shown, the first connecting module 22 is located between two adjacent battery swapping modules 21 perpendicular to the vehicle's travel direction. The first connecting module 22 is connected to the corresponding battery swapping module 21 at both ends perpendicular to the vehicle's travel direction. The first connecting module 22 forms a moving channel 52 for electric vehicles, facilitating their entry and exit from the battery swapping station and their movement to other battery swapping stations 26. This prevents vehicles behind from being blocked by other electric vehicles undergoing charging or swapping, improving battery swapping efficiency and user experience. Furthermore, the first connecting module 22 forms a gap between two adjacent battery swapping stations 26 perpendicular to the vehicle's travel direction to prevent collisions between electric vehicles.

[0107] In other alternative implementations, if there are no two adjacent battery swapping modules 21 perpendicular to the vehicle's driving direction, the first connection module 22 may not be provided.

[0108] like Figure 2 As shown, the second connecting module 23 is disposed between two adjacent battery swapping modules 21 in the vehicle's driving direction. The two ends of the second connecting module 23 in the vehicle's driving direction are respectively connected to the corresponding battery swapping modules 21. The second connecting module 23 is used to form a gap between two adjacent battery swapping stations 26 in the vehicle's driving direction to prevent collisions between electric vehicles. In other alternative embodiments, if there are no two adjacent battery swapping modules 21 in the vehicle's driving direction, the second connecting module 23 can be omitted.

[0109] like Figure 2 As shown, the first connecting module 22 is located between two adjacent second connecting modules 23 perpendicular to the vehicle's driving direction. The two ends of the first connecting module 22 perpendicular to the vehicle's driving direction are respectively connected to the corresponding second connecting modules 23, so that the two ends of the moving channel 52 are connected in the vehicle's driving direction, which facilitates the movement of electric vehicles.

[0110] like Figure 1 As shown, the third connecting module 24 is located on the side of the second connecting module 23 away from the first connecting module 22 and is connected to the second connecting module 23. Figure 5 As shown, the battery swapping station in this embodiment also includes a maintenance room 3, which is located between the two battery swapping rooms 1 in the vehicle's travel direction. In this embodiment, the width of the maintenance room 3 perpendicular to the vehicle's travel direction is smaller than the width of the battery swapping room 1 perpendicular to the vehicle's travel direction. The third connecting module 24 can fill the portion of the maintenance room 3 that is smaller than the battery swapping room 1 to ensure flatness.

[0111] In other alternative implementations, if the maintenance room 3 and the battery swapping room 1 have the same width in the direction perpendicular to the vehicle's travel direction, then the third connection module 24 may not be provided.

[0112] As shown in Figure 4 , the driving guide module 25 is arranged on at least one side of the battery replacing module 21 in the vehicle driving direction and is connected with the battery replacing module 21 and / or the first connecting module 22, and the upper end surface of the driving guide module 25 is inclined downward from the end close to the battery replacing module 21 to the end away from the battery replacing module 21, and the driving guide module 25 is used to guide the electric vehicle to enter or exit the battery replacing station.

[0113] Specifically, the bottom plate 2 is provided with the driving guide module 25 at both ends in the vehicle driving direction, one of which is used to guide the electric vehicle to enter the battery replacing station, and the other is used to guide the electric vehicle to exit the battery replacing station. The driving guide module 25 and the battery replacing module 21 and the first connecting module 22 adjacent thereto are connected to ensure the overall connection strength.

[0114] In other alternative embodiments, the driving guide module 25 can be connected only with the battery replacing module 21 or only with the first connecting module 22 when the connection strength meets the requirements.

[0115] The various modules of the bottom plate 2 in the embodiment are made of concrete, and the bottom plate 2 made of concrete has low cost. The various modules are separately formed and transported to the site, and then spliced together through hoisting process. How to fix the concrete modules belongs to the prior art in the field, and will not be described here.

[0116] In other alternative embodiments, the bottom plate 2 can also adopt an integrated structure, and the integration of the bottom plate 2 is realized by pouring cement. The first track 2131 and the second track 2132 can also be a pre-buried track structure.

[0117] In other alternative embodiments, the bottom plate 2 can also be made of other materials, such as steel. The bottom plate 2 made of steel has high strength.

[0118] Embodiment 2

[0119] As shown in Figures 4-6 , the bottom plate 2 in the embodiment is basically the same as that in Embodiment 1, and the difference lies in the connection mode between the various modules of the bottom plate 2.

[0120] Specifically, as shown in Figure 4 , the various modules of the bottom plate 2 in the embodiment are made of steel. The two adjacent modules in the vehicle driving direction and / or perpendicular to the vehicle driving direction are rotationally connected, so that after the various modules are assembled, the space occupied by the bottom plate 2 can be reduced by rotating the corresponding modules, facilitating transportation to the site, shortening the station building period, and meeting the demand of rapid batch station building in a short time.

[0121] Specifically, as shown in Figures 4-6 In this embodiment, the rotation connection between the battery replacement module 21 and the first connection module 22, the rotation connection between the first connection module 22 and the second connection module 23, the rotation connection between the third connection module 24 and the second connection module 23, and the rotation connection between the travel guide module 25 and the travel guide module 25 are convenient for folding the bottom plate 2.

[0122] In other alternative embodiments, the rotation connection between the battery replacement module 21 and the first connection module 22, and / or the rotation connection between the battery replacement module 21 and the second connection module 23, and / or the rotation connection between the first connection module 22 and the second connection module 23, and / or the rotation connection between the third connection module 24 and the second connection module 23, and / or the rotation connection between the battery replacement module 21 and the travel guide module 25, and / or the rotation connection between the first connection module 22 and the travel guide module 25 can be fixed by bolts or other fasteners, or by hinges or other rotating parts. When the modules are assembled and then transported to the site, the rotating connection between the modules allows the modules to rotate at a certain angle, reducing the overall area occupied by the bottom plate 2 and facilitating transportation.

[0123] Further, as shown in Figure 6 In this embodiment, the two modules adjacent to each other in the vehicle travel direction and / or perpendicular to the vehicle travel direction are connected by a hinge 5, and the hinge 5 is installed on one of the end surfaces of the modules in the vehicle height direction. The hinge 5 has a simple structure, high connection reliability, and facilitates the rotation and resetting of the modules. Moreover, the hinge 5 has a small structure and does not interfere with the travel of the electric vehicle.

[0124] Specifically, as shown in Figure 4 The hinge 5 includes a first connecting portion 51, a second connecting portion 52, and a rotating shaft 53, the first connecting portion 51 and the second connecting portion 52 are connected to the two adjacent modules respectively, and the rotating shaft 53 is connected between the first connecting portion 51 and the second connecting portion 52, and the rotation between the two modules is realized through the rotating shaft 53.

[0125] Further, as shown in Figure 5 and Figure 4 When the same module needs to be installed on both sides in the same direction, the hinges 5 on both sides of the same module are installed on both sides of the module in the vehicle height direction, so that the two modules adjacent to the module can be rotated in different directions, i.e. one module can be rotated from top to bottom, and the other module can be rotated from bottom to top, thereby increasing the rotation range of the two modules and further reducing the space occupied by the bottom plate 2.

[0126] Further, as shown in Figure 6 and Figure 4As shown, if two adjacent modules in the vehicle's driving direction and / or perpendicular to the vehicle's driving direction are not rotatably connected by hinge 5, they are fixedly connected by fixing plate 6. Specifically, battery swapping module 21 is connected to driving guidance module 25 by fixing plate 6, battery swapping module 21 is connected to second connection module 23 by fixing plate 6, first connection module 22 is connected to driving guidance module 25 by fixing plate 6, and first connection module 22 is connected to first connection module 22 by fixing plate 6.

[0127] In this embodiment, the fixing plate 6 is a cuboid plate-shaped connector, which has a simple structure and is easy to process.

[0128] In other alternative implementations, the connection between two adjacent modules can be adjusted to be either rotatable or fixed, depending on actual needs. It should be noted that the fixing plate 6 and the hinge 5 can be installed on different modules to achieve completely different connections between the two modules. However, if the fixing plate 6 and the hinge 5 are installed on the same module, then to ensure that the fixing plate 6 does not interfere with the rotation of the side of the module where the hinge 5 is installed, the fixing plate 6 and the hinge 5 should be installed on different sides of the same module.

[0129] Example 3

[0130] like Figures 7-9 As shown, the base plate 2 in this embodiment is basically the same as that in embodiment 1, except that the connection method between the various modules of the base plate 2 is different.

[0131] Specifically, such as Figure 7 As shown, each module of the base plate 2 in this embodiment is made of steel. Adjacent modules are fixedly connected in the direction of vehicle travel and / or perpendicular to the direction of vehicle travel. This fixed connection method provides high connection strength and prevents displacement between modules.

[0132] like Figure 8 and Figure 8 As shown, each module includes a support plate 71 and several support ribs 72 located on the lower end face of the support plate 71. The upper end face of the support plate 71 is used to support the electric vehicle, and the support ribs 72 are used to enhance the strength of the module while reducing the weight of the module.

[0133] like Figure 9 and ​ As shown, the support ribs of two adjacent modules in the vehicle's driving direction and / or perpendicular to the vehicle's driving direction are detachably connected by fasteners, facilitating the connection between adjacent modules. This detachable connection method also facilitates the maintenance of individual modules.
